I've installed the password protect extension and it works fine to protect pages and entry.

My Problem is how can the user logout byself and by the server/administrator.Once the user is logged in, he can visit all sites every time !? If he closed the browser the session ist destroyed and the user is logged out, but if he leave the browser open ...

The password protect extension is not that sophisticated. Maybe you could ask hansfn (the author of this extension) what your options are.Perhaps there is a cookie created somewhere that you can delete by an optional log out button?

Quality is in the detail of things............
